Born 1973-Oct-04. Japanese pro 5-dan[2] in the Nihon Ki-in, credited with technical advice for Hikaru no Go[1]. She stars as the teacher in Go Go Igo.
Here is her official website.
Jan van der Steen's brief GoBase biography links to 15 games by Umezawa-san, and let me find
photo albums at Nihon Ki-in.
A fan has collected some photos of her (this link appears to be dead). There is a short
Umezawa Yukari profile at MSOworld.

Regarding Hikaru no Go, Pieter Mioch wrote in rec.games.go (2001-Dec-02):
[2]: September 11, 2002 - The Nihon Ki-in's news in English reports that Umezawa Yukari has been promoted to 5 dan. Apparently celebrity status and a busy agenda dominated by Hikaru do not prevent her from performing well in the Oteai. --Stefan
Her record can be found on her website. This busy August she was 4:1. --HolIgor
